| Discussion | Varieties 2 (2 in the flora). Ribes sanguineum is widely cultivated. It begins to bloom very early in the season, providing a nectar source for pollinators when little else is available. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Ribes quercetorum occurs in the foothills of the Sierra Nevada, the inner Coast Ranges south to the western Colorado Desert in California (and into Baja California), and the mountains of south-central Arizona. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
